How to use a box scraper?
Running the box scraper will do about 90% of the work of maintaining your road. Leave the tines in the "up" position and just use the blade on the bottom to scrape the surface. Depending on the width of your scraper and your road, you simply run up/down the road until the entire surface has been scraped. What happens is that the scraper will pick up gravel and dirt until the box is full. Then, the material will be redeposited on the road in an even layer. This will scrape high points and fill-in low points. For the first time, you may need (want) to run over the surface a few times -- after initially getting the road (relatively) smooth, monthly maintenance for heavily-traveled neighborhood roads and quarterly maintenance for a driveway works well.
